Maths :How much time will a 500 m long train take to cross a tree if it is moving at a speed of 72 (Hint: Take the length of the train as the distance.)​

Complete question:

How much time will a 500 m long train take to cross a tree if it is moving at a speed of 72 km/h

(Hint: Take the length of the train as the distance.)​

The time taken for the train to cross a tree is 25 s.

Explanation:

Given;

length of the train, L = distance between the train and a tree, d = 500 m

speed of the train, v = 72 km/h

Convert the speed to m/s, since the unit of the distance is in meters;

The time of the motion is calculated as;

Therefore, the time taken for the train to cross a tree is 25 s.

i say that the answer is 'd'
